Discussion Overview

The discussion revolves around the concept of starting life on another planet, exploring various methods of colonization, terraforming, and the challenges associated with these processes. Participants consider both Earth-like and non-Earth-like conditions, as well as the implications of introducing life forms to new environments.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that colonization could begin with traveling to a habitable planet equipped with necessary tools and life forms.
  • Others propose that life could be started even on planets that do not resemble Earth, potentially through methods like pollution or terraforming.
  • A participant mentions the idea of sending various animals and plants that could survive in the new environment to establish a sustainable ecosystem.
  • There is a discussion about terraforming as a hypothetical process to modify a planet's conditions to make it habitable, with references to existing threads on the topic.
  • One participant raises the feasibility of mining chemicals from gas giants and using autonomous robots for terraforming efforts, although they acknowledge significant engineering challenges.
  • Humor is present in the discussion regarding the origins of life and the nature of potential alien offspring.

Areas of Agreement / Disagreement

Participants express a range of views on how to approach colonization and terraforming, with no clear consensus on the best methods or feasibility of the proposed ideas. Multiple competing views remain throughout the discussion.

Contextual Notes

Some claims depend on assumptions about technology and biological compatibility, while others highlight unresolved engineering challenges related to resource extraction and terraforming processes.

Assuming we can ever find another habitable planet and can get there, how the heck would we start to colonise it.
If there is water, vegetation and there is~the same climate of Earth.
 
Biology news on Phys.org
To get the rough idea, play alpha centauri.
 
I would assume by traveling there with an array of equipment.
 
We can even start life on planets that do not resemble Earth. We should start by polluting it.

Well wolram - a mummy physicist and a daddy physicist who love each other very much have a special sort of cuddle and ...
 
infect it. send sheep. fishes. piggies. whatever can survive on the vegetation and is useful and not a threat to us. and other vegetation, like fruits and legumes, that are useful to us. we show up a few years later when the populations of these animals are at sustainable levels, with knives and shears and spears.
 
You don't even need to have the same conditions presently found on earth, to colonize a planet. There is a concept of terraformation or planet engineering. There are lots of discussions on how to accomplish this. Here is a one http://en.wikipedia.org/wiki/Terraforming" .

Terraforming (literally, "Earth-shaping") of a planet, moon, or other body is the hypothetical process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to those of Earth to make it habitable by humans.
We also have some threads on terraformation. Here is one on https://www.physicsforums.com/showthread.php?t=199582".

If a planet already has the same conditions we have on earth, all we need to do is; build an ark, fill it with life, and take a trip over there and set up shop.. It would be a good idea to try out all the lifeforms in an *engineered biosphere on Earth first, to make sure we didn't forget to bring along something important. :rolleyes:

*engineered biosphere - this concept was attempted in the Biosphere2

You mean some guys dips their wicks and nine month later we have some little candles.

I've always wondered if mining chemicals out of the gas giants will ever be feasible; there seem to be lots of engineering problems surrounding that. But if so, and if it could be done with some sort of autonomous robots, it seems like they could be used to fling blocks of water ice and whatever else would be needed for terraforming towards Mars or Venus. After a few hundred years of that maybe we can start selling real estate.

Yes, but this is on another planet, so the spawns would spit acid and have 5 legs. I mean, they're aliens, right?

That's the problem with all of these get-rich-quick schemes. They're not quick. Hundreds of years? I don't have that kind of time. I got things to see and people to do.

So, give me more time and I'll be able to wait until your shiny robots painstakingly transfer ice from a red giant 3 AU away 1kg block at a time.
